A turbine engine debris ingestion monitor has an acoustic emission sensor 18, 18a mounted on a surface 14, 14a disposed in an air flow stream of a turbine engine 12. The sensor converts acoustic emissions 16, generated by particles of debris 10 impacting on the surface, into an electrical signal. A counting circuit 22 (FIG. 2) processes the signal resulting in an output, indicative of the level of debris ingested into the engine, which is recorded in the aircraft's flight data recording system 110.
